Hello,
I need some help with FormTester and Ajax.I want to test a form, in which the
second dropdown is updated in ajax when we change the first dropdown.The form
is working fine but I can't manage to test it.
DropDownChoice<Company> companyDropDownChoice = new DropDownChoice<>(
"company", LoadableDetachableModel.of( ()-> getCompaniesList() ), new
CompanyChoiceRenderer<>() );managerDropDownChoice.setRequired( true );form.add(
companyDropDownChoice );
DropDownChoice<User> managerDropDownChoice = new DropDownChoice<>( "manager",
LoadableDetachableModel.of( () ->
getUserList(companyDropDownChoice.getConvertedInput()) ), new
UserChoiceRenderer<>() );managerDropDownChoice.setRequired( true );form.add(
managerDropDownChoice );
companyDropDownChoice.add( new AjaxFormComponentUpdatingBehavior( "change" ) {
@Override protected void onUpdate(AjaxRequestTarget target) {
target.add( managerDropDownChoice ); }} );
//testFormTester formTester = tester.newFormTester( "form" );formTester.select(
"company", 0 );tester.executeBehavior( (AbstractAjaxBehavior)
tester.getComponentFromLastRenderedPage( "form:company" ).getBehaviors().get( 0
) );formTester.select( "manager", 0 ); // Throws
java.lang.IndexOutOfBoundsException: Index 0 out-of-bounds for length 0
Of course I made sure that for the company at index 0, getUserList() returns
some items.Also, I made sure that when calling tester.executeBehavior,
getCompaniesList() is indeed called. It's more like if formTester does not
update the dropdown...
What am I missing?
Thanks in advance,Virginie
